" Application man a-20,1914. Serial No. 833,259.

To all whom it may concern:

Be it known that I, JOHN Hnrr ann, a citizen of the United States,residlng at SaXton, in the county of Bedford and State of Pennsylvania,have invented a new" and useful Plow, of which thefollowing is aspecification. 1 V

The present lnvention appertains to plows or earth tilling implements,and aims to provide a novel and improved device of that character.

The present invention contemplates the provision of aunique cutterattached to the shovel blade of a plow in a peculiar and effectivemanner, whereby the plow will be,

tion, in order'to enhance the utility of the plow, and to provide astructure which will be comparatively slmple and inexpensive, as

well as being practical,-convenient and efficient in its use.

lVith the foregoing and other objects in view which will appear as thedescrlptlon proceeds, the invention resides in the combination andarrangement of parts and 1n the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing fro-m the spirit of theinvent on.

The invention has been illustrated in its preferred embodiment in theaccompanying drawing, wherein Figure 1 is a side elevation of theimproved plow. Figs. 2 and 3 are sectional views taken on the lines 22and 3-3, respectively, of Fig. 1.

The present implement embodles a suitable beam 1 having a standard 2attached to its rear end, and having handles 3 attached thereto inadvance of its rear end and between which the upper end of the standard2 is secured in any suitable manner.

A stay rod 4 is preferably provided for holding the lower portion of thestandard 2 in place, the ends of the stay rod 4: being engaged throughthe beam 1 and standard 2, so that the intermediate portion of the rod4:

will extend diagonally or obliquely between the body of the beam 1 andthe lower or depending portion of the standard 2. A nut 5 is preferablythreaded on the rear end of the rod 4 to hold the lower portion of theard to be adjusted by tightening or loosening the nut5. The plow furtherincludes a shovel blade 6, which is preferably curved slightly, andseated against the lower curved portion of the standard 2, the upper endof the blade 6 having a lug 7 engaged upwardly through a staple orkeeper 8 engaged to the forward side of the standard 2 below the stayrods. The central portion ofthe blade 6 is secured firmly to the lowerportion of the standard 2, by means of a bolt 9 engaged through thestandard 2 and having a countersunk head 10 at its forward end engagingin a countersunk recess within theforward side of the blade-6, in orderthat the head of the bolt 9 will be flush with the face of the blade. Anut or retaining element 11 is threaded or otherwise engaged upont-herear end of the bolt 9, to clamp the blade 6 tightly against thestandard, and to hold the retaining lug 7 of the blade in engagementwith the keeper 8, whereby the bolt 9 and keeper 8 will hold the bladesteady, and will prevent the displacement thereof relative to thestandard, although the blade may be readily detached from the standardwhen desired.

One of the salient or cardinal features of the present invention residesin the provision of a cutter 12 disposed vertically upon the face of theblade 6, the forward edge of the cutter 12 being sharpened, and its rearor basal edge being thickened and having side flanges or lips 13 restingagainst the face of the blade 6. The lips 13 have their free edgessharpened, in order that the faces of the lips 13 will merge into theface of the blade 6, to provide a practically continuous surface betweenthe side portions of the blade 6, and the lips 13. The faces or sides ofthe cutter 12 and its lips 13 also blend together gently, as seenin-Figs. 2 and 3, whereby there will be no obstructions or protuberanceswhich would interfere with the action of the shovel, or which wouldserve to accumulate dirt and other extra neous matter.

The cutter 12 is secured to the blade 6 by means of screws orothersecuring members I standard 2 in place, and to enable the stand-14- engaged through the lips 13 and taking into or engaged through theblade 6. A- plurality of screws or securing members 14: are preferablyengaged through each of the lips 13, whereby the cutter 12 will be mosteffectively secured to the blade. The cutter 12 extends to the lower endof the blade 6, and tapers downwardly, in order that the forwardsharpened edge of the cutter will extend to the lower end or extremityof the blade 6, as seen in Fig. 1.

In practice, the present plow is employed in the usual manner fortilling or breaking the soil, and is particularly desirable for breakingopen new ground. The cutter 12 will split the soil open, whereby thesoil will be thrown or deflected to the opposite sides by thecooperating lips 13 and side portions or wings of the blade 6, tothoroughly agitate or break open the soil. The cutter 12 will also severthe roots encountered thereby, so as to not only destroy the roots, butto permit the plow to continue the tilling of the soil withoutinterference. Shouldthe cutter 12 become dull aftercontinueduse,3 thesame may be sharpened, preferably-byi removing the cutter and sharpeningthe i same in any suitable manner. The cutter 12 i may be removedreadily from the blade 6, by withdrawing or removing the securingimembers 1 1. Thus, the cutter may also bei removed, when it is desiredto utilize the ing basallips resting against the blade and having theiredges sharpened whereby the faces of the lips merge gently into the faceof the blade.

2. A shovel blade, a vertical cutter having sharpened basal lipsfittingagainst the face of, the blade, and securing members engaged through thesaid lips and through the blade.

3. A shovel blade, a vertical cuttebhavving basal lips resting againstthe face of the blade, and means securing the said lips to the blade,the faces of the cutter and said lips blending together gently, the freeedges of the lips being sharpened whereby the faces ofthe lips mergegently into the face of the cutter, and the cutter being tapereddownwardly.

In testimony that I claim the foregoing as my own, I have hereto aiiixedmysignature in the presence of two witnesses.
